Fatty acids are very soluble in glycerol or the PEGs. Most proteins tolerate high concentrations (30-50%) glycerol and PEGs.� So, it is quite possible to make a solution that will allow the protein crsytal and the ligand to both be in the same solution. One of my former colleagues was in

Hi Frank, heme becomes near completely insoluble when it dimerizes. Fatty acids are also very insoluble. It is quite hard to get them into HSA, as far as I remember. Cheers, Tim On Wed, 23 Jun 2021 10:33:42 +0100 Frank von Delft wrote: > And then of course, you need to decide whether you at

And then of course, you need to decide whether you at all care to know anything about a compound that is so insoluble that it needs that kind of treatment :) On 23/06/2021 09:52, hoh wrote: Hi As total insolubility does not exist, I regularly use another method, which is to deposit a

Hi As total insolubility does not exist, I regularly use another method, which is to deposit a grain of the ligand directly into the drop. In this case, we no longer control the concentration. The goal is to regularly freeze crystals (1 hour, 2 days, 1 week ..). Depending on the results, it

Dear Gourab, You might just want to add the ligand in pure, solid form to the edge of the crystallization drop. This worked in our case beautifully (see Angew. Chem. Int. Ed. 2012, 51, 3354). We had to soak it for 4 weeks. Good luck! Best regards Bernhard
